My concern is either Port or Starboard install, you will lose one half of your signal because of the turbulence from the prop and rudder. I'm guessing you will end up with a Port AND Starboard transducers hooked together with a "Y" cable. Wait for more feedback before you go this route.

I suspect that you will, but you might be able to live with the results. No one knows until you see the images. Depending on the location, it might shoot underneath the trust. If it doesn't work, at least you have a backup plan. Good luck.

Now the decision is : do I put the boat in the water like this to test for turbulence/ interference and run the risk of having to pay another haul out/ put in fee if the second transducer needs to be installed OR pay for the second transducer and install it now. Good luck which ever way you go.
